Rebecca is a name representing beauty in the Bible, an Old Testament classic that reached the heights of revived popularity in the seventies but is still a pretty and prudent choice. The Becca short form is more stylish now than homespun Becky. The biblical Rebecca was the wife of Isaac and the mother of Esau and Jacob. Rebekah was a common form of the name in the bible.
Rebecca's popularity dates back to the Colonial period; after records started being kept, she hit the Top 100 in 1940, and eventually was in the Top 15, now ranking at Number 184. Nickname Becky is a staple in such classics as A Little Princess, The Adventures of Tom Sawyer and Vanity Fair, while the full form features in the eponymous Daphne du Maurier novel, in Ivanhoe and Rebecca of Sunnybrook Farm.
